Prime Minister Charles Michel refused to accept the resignations of the interior and justice ministers after Turkey said it deported airport bomber Ibrahim El Bakraoui and warned Belgium that he was a "terrorist foreign fighter", but was ignored. Hundreds of people gathered late into the night at the Place de la Bourse square in Brussels, carpeted with candles, balloons and flowers as people pour in constantly to pay tribute to the victims.
"Our love for Brussels is stronger than terror," read a banner held by a grieving young couple. Led by King Philippe, Belgians also observed a minute of silence on the third and final day of mourning for the 31 people killed and 300 injured in Tuesday's attacks in the symbolic heart of Europe. Harrowing new footage of the moments after the Zaventem airport attack meanwhile emerged on Belgian television, showing a lone baby left sitting crying in the wreckage next to the lifeless body of a woman.
With criticism growing that international authorities failed to follow links between Tuesday's bombings and the attacks on France in November, key Paris suspect Salah Abdeslam insisted he was unaware of plans to strike the Belgian capital. Police arrested Abdeslam just around the corner from his family home in Brussels on Friday, after he spent four months on the run as the last surviving member of the attackers who killed 130 people in Paris. Abdeslam's lawyer Sven Mary said Thursday his client now did not want to fight extradition to Paris and insisted Abdeslam "didn't know" in advance about the Brussels attacks.
But Belgium is reeling from revelations that three of the Brussels attackers - including Ibrahim El Bakraoui and his brother Khalid, who bombed Maalbeek metro station - were known to police and had strong links to Abdeslam. Interior minister Jan Jambon and Justice Minister Koen Geens both tendered their resignations over the claims that Ibrahim El Bakraoui had slipped through the net despite being arrested by Turkey near the Syrian border and deported to the Netherlands. "There were errors at Justice and with the (Belgian) liaison officer in Turkey," Jambon was quoted as telling the Le Soir daily.
Prosecutors meanwhile confirmed that Khalid El Bakraoui was the subject of an international warrant for terrorism in relation to the Paris attacks and had rented out a flat used by the Paris cell in the Belgian city of Charleroi. Belgian authorities are now seeking a new suspect with a large bag seen talking to Khalid El Bakraoui on CCTV footage at Maalbeek station, who then did not get on to the train with the bomber, police sources told AFP.
A huge manhunt is already under way for a third attacker whose bomb failed to go off at Brussels airport, a man wearing a hat seen on security footage with Ibrahim El Bakraoui and another attacker identified as Paris bomb-maker Najim Laachraoui. Belgian Taekwondo champion Mourad Laachraoui, who is Najim's younger brother, issued a statement saying he "firmly condemns the actions of his older brother and the attacks in which he was involved in Paris and Belgium."
The attacks have stunned Brussels, home to the headquarters of the European Union and NATO. Belgium on Thursday lowered its terror alert to the second highest level for the first time since the attacks, but soldiers still guarded key sites, streets were eerily quiet and public transport shut down again in the early evening. EU justice and interior ministers convened in Brussels for an emergency meeting to show "solidarity" to Belgium and work out a plan to address the threat to Europe posed by jihadists.
"The attacks did not come as a surprise," said European Home Affairs Commissioner Dimitris Avramopoulos, calling on EU nations to push through plans to share the names of all air passengers. People of around 40 nationalities were killed or wounded in the attack. Very few of the dead have been formally identified but stories were emerging of lucky escapes and tragic ill fortune of people caught in the wrong place at the wrong time.
A young German couple headed for a New York holiday after their wedding last year were among the victims of the Brussels airport attack, which left the wife missing and the man in a coma, the Bild daily reported. Adelma Marina Tapia Ruiz, a 37-year-old Peruvian woman, was killed by the airport bomb but her two young daughters and husband survived because the twin girls had run off and the father was chasing after them. US Secretary of State John Kerry is due to arrive in Brussels on Friday in a show of solidarity, during which he will pay tribute to the victims at the airport.
